A septase-null cell that expressed RFP-α-tubulin (red) and GFP-myosin II heavy chains (green). The cell shows first wave-like depletions of myosin II that were independent of microtubule structures, and subsequently areas of depletion at the microtubule aster regions. These depletions are also seen around single centrosomes that are not connected by a spindle. This movie is related to Figure 5.
